I run a 6wt Ambush on my 8 wt. single handers. I add a Delta spey replacement tip 6/7 sink 3 or sink 7 primarily. This is a 13' tip that I cut back to 9'. This puts the sink tip at about 50g. I've also cut back an intermediate 6 wt. Versi-Tip to 50g and it works well. With this configuration, there is minor overloading on overhead casting at about 65-70' where the loop wants to tail. An 8 wt. single hander is lined perfectly with this rig for single hand spey. I can get a demo line & tips in the mail tomorrow if you're interested. firstname.lastname@example.org Ed Oh, and it's also a great 6wt shooting head line as well as a gem to cast on the Echo SR 5 wt. switch.
