In my opion I would put rank them scn20bw, 17bh, 18 and 19, I would also agree with bulldog scn18bh is a better stick with 20bw being close. The 18 defiantly needs break in along with 19, both scn20bw 17bh much hotter out of the wrapper.
I have loved my 20BW from the get go, but it continues to get hotter especially around the 1500 swing range. 17BH is definitely hot but I prefer the one piece bats. Just picked up an 18, but will wait to review it until it has at least 1000 swings or so
I'd rank em SCN17BH > SCN19 > SCN20BW, never swung an 18. Its all a matter of personal preference, one piece vs two piece, varying amounts of end load, size of sweetspot. Can't go wrong with any of the three.
I just got my SCN17BH Wednesday. Good thing I'm doing bp Saturday and Sunday Gotta break it in. I know it took my SSR2 800-1000 hits to finally open up, how long does it take for the SCN17BH to open up.?
This is all personal preference the 4 bats you named are all good bats when broken in just matters what you like. SCN17bh 2 piece 12 inch barrel, SCN18 1 piece 13.5 inch barrel, scn19 2 piece 13.5 inch barrel, SCN20BW 1 piece 12 inch barrel.
Best bet pick one up you think you will like, swing it and if you don't like it trade it for something else.
