I got the ren epic waters 7127-6 a couple weeks ago, different rods but close cousins I imagine. I used the undertaker 35, 400+375 and the tributary 475 I had for my 6 weights. All the lines felt great but the 400 grain undertaker is my favourite for sure.

 

I have one I just love it! I tried the tributaries on that one as well as my 14 foot 7 weight NAM and there ain’t nothing better than an Airflo 480 compact scandi on those rods...I consider myself a fair touch and go caster with excellent sustained anchor abilities with some shmancy hybrid stuff when needed and I can’t for the life of me get those Bridge lines to work for me at all. I’ll be putting them up for sale tomorrow if interested for your future 7126.

Your leader is probably wrong with the trib if you can't make it work, they are easier casting lines than the compact.

 

I would query Barrett; he was extremely forthcoming with suggestions for lines for 7140-5!

Parera - How long do you like your leaders with the Bridge Tributary lines? I was using a 15' custom leader on a recent trip with the Nam REN 7140-5 that Barret's group joined and he said he like a shorter leader on this specific rod.

 

I went shorter too; 13' with about the butt being 20lb Max UG and the rest being 10 lb UG which in most situations include a 2' section of zentai (I've been using the bridge mainstem on it too and went even shorter due to extra stick from the line itself).
