Lots of ideas and they all work.You can use a 6-7 ft piece of #20 mono on your floater with no problems.For my intermediate I use about 5' of #15 mono for my 8wt and #12 for 6 & 7 wts.If you want to tie your own leaders,use a 60-20-20 formula.Make the butt section 60% of the leader,the mid section 20% and the tippet 20%.For this I have used 4' of #30 mono for the butt,2' of #20 for the mid and 2' of #15 or #12 for the tippet.I use a surgeon knot for the butt to mid and a perfection loop for the mid to tippet.My feelings are that floro is mostly hype and is not needed so I go with mono.Its cheaper and the fish just dont care.
