Thanks for the love guys!! Oh no, somebody noticed!! Yeah, it really really annoys me - I'm re-doing it next time I drain the loop (that's one of the reasons for the drain). When I originally did the bend I was working with a 20cm bending insert, which simply wasn't long enough to go up (from shroud to first bend) and then around the bend, so - I made the up part as long as I could with the insert I had and went with it... Can't wait to rip the thing out though! Bit of advice for anybody thinking of working with hard tube - find the longest darn insert you can as a priority!!
