Most of my partners prefer it when I don't give them 3 card support initially. That being said, if I had only 5♣ or my 6 card suit were really trashy, I'd bid 2♠ here.

While this is somewhat of an oversimplification, it seems like raising is often good when partner has exactly five spades (reaches a better partial when partner's passing, sets the suit in a non-awkward way, etc) whereas rebidding clubs is often good when partner has only four spades (better partial, more room to negotiate for 3NT, etc). Assuming we have this shape and partner has a 1♠ response, I ran a simulation to find out how many spades partner should hold. The results:
(1) Assuming a style where a 1♠ response can contain much longer diamonds (i.e. 1♠ response shows 4+♠ and not exactly 4-4 in the majors) partner will have exactly five spades about 45.4% of the time, six or more spades about 16.8% of the time, and exactly four spades about 37.8% of the time.
(2) Assuming a style where a 1♠ response denies holding five diamonds with only four spades (i.e. 1♠ shows 4+♠ but not exactly 4-4 in the majors and not 4♠ and 5+♦) then partner will have exactly five spades about 50.4% of the time, six or more spades about 18.8% of the time, and exactly four spades about 30.8% of the time.
Again, there's obviously more to it than this. What works best for you will depend on your methods after the single raise, your methods after the 2♣ rebid, exactly when you respond 1♠ versus 1♦ (versus raising clubs?) and so forth. The tradeoffs are not exactly clear, nor are the relative sizes of gains and losses. But it does seem that partner is more likely to have exactly 5♠ than exactly 4♠ by a fairly substantial margin.

Adam I think you are missing something. Let's agree that it only matters if partner is less than invitational, since if he takes another bid we can go to spades. In that case the opponents often balance, or maybe LHO doubles 2♣ with the red suits, and then we can bid 2♠ freely next round and really get our hand across. Obviously then we not only recover when partner has 5 spades but we don't risk him having 4 spades, we are way ahead of someone who raised directly and might even have been invited to the 3 level based on a fit.
Also it's imps. If 2♠ makes then 2♣ probably makes given how good our clubs are, but I think the opposite is true far less often. In other words the cost of 2♣ when partner has 5 spades is a lot lower than the cost of 2♠ when partner has 4 spades imo.

I also want to add that it's not like bidding 2♠ is a magic ticket to bidding every making game when partner has spade length. You will often not get there anyway.
Good comments by jdonn and awm.

T-Walsh is cool when you want to show 3-card support without bypassing 1NT or 2♣, but with this particular hand I see no serious downside to just bidding 2♣.
I don't like raising on 3 too often. If p tries for game over it, 2NT, 3♣ or even 3♦ could be the last making contract. It is even worse when people raise 1♥, bypassing a 4-card spades. Then all five denominations are still open.

Still, with a singleton I think I can survive this one. 2♠ it is. Had it been a 3226 I think 2♣ is preferrable.

isn't "often" a significant overbid?

This is a close decision if the Q♦ were the K I would probably, I didn't look so assume IMPS, bid 2♠ to goad partner to a close game.

The flip side of this is that maybe it's more difficult for the opponents to compete if they have to commit to the 3-level.

Another point is that there's a correlation between opponents balancing and the size of the club fit. When you rebid 2♣ into a 6-1 fit, opponents are much more likely to pass you out than when you rebid 2♣ into a 6-3 fit. This makes using the balance to push you from a poor club fit to a better spade fit more dubious.

I guess you are more sympathetic than you used to be wrt people who spell names incorrectly despite it being right in front of their faces
Anyways I would bid 2S with this hand, I don't want him to pass 2C when we make 4S.
