RE:clear intermediate lines
Tom, I went through a few flylines last summer and although I can't really recommend a line I loved, I would recommend that you stay away from the SciAnglers line. I bought mine at LL Bean's(great return policy) and after the coating on the third one started cracking and coming off I decided to get a refund instead of exchanging it yet again and I went with a Rio aqualux line. The Rio was a little more durable than the SciAnglers, and I liked the way it cast a bit better, but it too was starting to crack by the end of the season, so i'm still not satisfied.
I'm probably going to go with an air-flo this season and hope that the 5 year no crack guarantee is for real.
