If I went OL I'd commit for the full season, both to give them a fair shake and to satisfy my curiosity. There's always an adaptation period for new irons, and maybe even more so when going to OL(?), so a few rounds would be too small a sample size for me. Give me a full season, with all its ups and downs, and I'd have a good idea of whether I should stay all in or switch back.
Thats my big argument. I really wanted to go OL last year but being selected late I would have had about 3 weeks to figure it out. I chickened out. I wish I would have gone for it looking back. And I'm not the only one.
