I planned on cutting one polyp off, one of the adults on the right side of the frag in the picture, leaving the new polyp on the left and one of the other adult polyps. I can get right between those 2 adult polyps with ease.
I think these are mature enough to frag as i just got in 4 more colors of duncans and all of them have smaller polyps that these. And after seeing how Tyrone chops these things up, i really think its hard to go wrong.
Thanks for all the info and advice guys. I'll let you know how the fragging goes.
