I don't understand why everyone has problems shooting through a 25. . .I never have problems?? I shoot 27's all the time 1cc takes me about 15 sec's, I've never had a problem.
What kinda sticks are you guys using?
Maybe it's because I use terumo's and they are supposed to have ultra thin walls. This is from the terumo website:
The Ultra Thin Wall Needles are allowing to choose a smaller, more comfortable gauge size with increased flow rates over Regular Wall or Thin Wall Needles.
Additionally, injection fluids with a high viscosity can be injected more smoothly than with standard needles.
