Replacement for Celestion G12T 100

I borrowed a Celestion G12T100 speaker to try with a 12 watt, 2 6V6 amp, sounds pretty good, maybe a hair bright,but I need to return it. What would you recommend, similar but better I guess for lack of a better term!

1st Choice: ET65

2nd:  Reaper or Reaper HP

Thank you. We have put the G12T100 in a home made 3/4 inch particle board Iso Cab, 24"x17",lined with 2" acoustic pyramid foam. Now TOO bright! Same recommendations?

Yep :-)
