Ultimately, you're responsible for hitting your ball.
But if the other guy knew it might be his ball (because the other guy was farther to the right, or hit it farther, or whatever…) then he could have warned the other guy.
Since posting the request for a used set, I've purchased a 5-sw set of new "Pin Hawk" heads, bent to 9 iron lie. I then had my local Dicks S.G. install shafts and oversize (1/6) grips.
They ended up about 7 iron length, which didn't accomplish what I was after due to the lie angle (and the fact that I suck with 7 iron length and up), so had then cut them down to 9 *no charge*.
Much better, but now those shafts are too stiff (original cut being for the 7 length), and can't get in the air good with the longer ones, so one more trip for softer shafts and I should be good.
For those saying "if it worked, all the pros would do it"....
I'm new to golf but now have a summer of playing under my belt, and I can tell you for sure these single length irons have made my first year "very tolerable". Had I been stuck hitting longer irons there wouldn't have been any point in going. *** I *** can't hit a good long iron (at least not yet), but my drives are decent and my short game is quite good for a newby, so this is an excellent option for me. The pros don't NEED them.
PS, I should add that the "Dicks SG" guy (Mike Gallaway) was awesome, and the length thing was my fault not his.
