I use 25 gauge only for everything. Its slow but will go. Heating definately helps but is not absolutely nessesary. Now a guy in the BB scene uses insulin needles exclusively. He puts everything through them also. It just takes time, alot of time. He uses slin pins because he believes there is less scarring of tissue. And after seeing his upper legs without a tan I understand why he uses slin pins.
