I just bought the speedy 25. I've been wanting either that or the speedy 30. When I bought my 25 they were out of locks so they told me to come back in about 1-2 weeks, but I've been thinking if I should change it for a 30. =/ I'm not sure though. What do you guys think. I'm 5'2-5'3 if that helps at all. I don't want it to over power me but I'm not sure which will be better. Advice please!
