I am not a pattern flyer but heres my 2 cents:
- do you have goals (win them all)? Fly because you enjoy it? Do you need to look for the ultimate in performance?
- are you using glow or electric now, or comfortable with both?

*** I am pretty comfortable with electric but glow stuff makes me a bit nervous. That would be reason enough for me to stay with electric. The same might work the other way too. ***
