Hi mate,
I reckon the Tcurve is no good. I have a 15kg Blue Water spin model and it is sloppy, heavey (honestly, its tip must be 8mm diamenter), has no underbinds, cheap reel seat, crappy epoxy job and a ferrule which never locks in properly and if it does, you can't get it apart. Try a Carpenter or Smith. Alternatively, get one made!!
