A bit late in replying (been sick the past couple weeks) so sorry for the late reply, but I've built around 20-30 rods on Fly Logic blanks. Pretty good blanks for the money. Their main three series are FLP, FLO, FLO+. Not sure if they still make the FLP series but I didn't care much for the FLP's. Pretty slow action and the butt diameter was HUGE on that series. A 5wt had a butt dia of about .440

The FLO and FLO+ are very nice though. Super fast action, nice finish and smaller more normal butt diameters. Pretty good place to deal with (fly fishing shop on ebay) but I know they did raise the prices last year. Use to you could get a FLO for well under $50 but last couple I bought from them we're about $70-$90 if memory serves correct. Havent bought one in about 4 months though so not sure what they are now.
