You've got a point Duggan, it's also nice to wear gloves and not have to deal with a lot of finger work. At the same time, it's also nice to be able to throw virtually any tip density using the Mike Kinney recipe head system as well despite lots of stripping and shooting, the likes of which would be very hard to achieve on a long belly line. No easy answers!
I guess working the softer seams and fishing a workable tip on a long working length of line would be the best way to go. I recall fishing a DTF 9wt cut and looped with a short 8wt type IV head in winter without taking the gloves off for long periods of time, and catching fish on it by working inside lies.
Sounds like the new 9140 might be a suitable tool for this approach listening to the reports. I'll bet the next set of freshets really gets things going in a hurry out there!
