One thing I learned playing the weight game to carbons......
I run Goldtips......two 50gr brass weights added to reg aluminum insert is about it, as amount of shaft that can flex has been reduced.
If you do that, might as well yank 'em and just go brass insert (100gr).
I ran 400's in a cut past center Blackwidow, 55# w fast flight.
Reg insert and one 50gr brass insert had it shooting bullet holes in paper. And my shafts were a tad long. 125gr tip.
If your Bear isn't cut past center or running FF my guess is your gonna need a 100gr brass insert and a tip weight over 125 gr. When using 400's.
Sacrifice one arrow to testing
Ran slightly shorter 400's in a 60# cut past center widow, B50 strung.......100gr brass insert and 125gr tip. Wonderful.
Those arrows will not work in my 48# cut past center Widow that's B50.
Maybe if I slap on a 225 gr head.
I have yet to try that (have some tips).
Beautiful paper tune with my GT 35/55. They are slightly shorter than the 400's from the last Widow. Shop ordered them (raw shafts) and they were shorter from the manufacturer. Probably thinking for smaller shooters? They work fine, but only because I draw right around 28".
Longer I might not have needed the weight added.........a little zip helps in 3D shooting LOL.
