The BBK’s are much better than the power kits as its only top section thats differant. The no3’s are standard and are fine for most situations but if you are fishing very long go for the MT3 as with the no1 removed they will do just about everything you ask of them.
I got 4 BBK’s with mine, fitted 2 with red hydro for munters and margin fishing and sold the other two to buy more MT3’s. If I’m fishing shallow I don’t want red hydro anyway so never an issue.
I am quite happy using really tight 16 solid but I know loads who even put red hydro through the MT3’s without any issues.
