I have shot the 3 blade 125's the 3 blade 100's and the 90 4 blade.I had best flight with the 4 blade.these little 90's will do the job.you could use 100's too.I shot a deer a few years back with the 90 4 blade and it didn't go 20yds.I think you will like the 4 blade better.you can pic any of them up on ebay alot cheaper than your local archery shop.
