Default newbie 20br question

I've read the threads about barrel twist. The 1:9 is popular for heavy bullets, and 1:11 is popular for 39/40 gr. bullets. My question is how would a 1:10 twist work with both heavy and light bullets? I'm interested in shooting mainly light bullets, and occasionally heavies.
Thanks.

Default 20 caliber twists

I have a 1 in 9 twist and it shoot 32 Gr Blitzkings very accurately with good velocity. So fast twist doesn't always mean lighter bullets aren't going to shoot just as well.

I have a .20 Tactical and a .204 that both have 1 in 12's and both shoot both the 32's and 40's with a slight accuracy edge going to the 32's at least in the .20 Tact. I have two smaller .20's that drive tacks with the 1 in 12 and 32's.
When I made my .20 Dasher I used a 1 in 11 as a little extra insurance for the 40's cause some seem to find the 1 in 12's a bit problematic with the 40 V-Max and while I haven't used em I'd bet dollars to dough nuts the 1 in 11 would do very well with the lighter bullets also.
If I were contemplating what you mentioned, being the 32's and 40's I'd use a 1 in 11 but I'm sure the 1 in 10 might well work just fine also.
Let us know what ya come up with and how it works ok?
