Medium Pips Or Longpips

Can anyone tell me if Medium Pips have the same technique as long pips, i would like to change over and try pips, so if i use Medium pips to start with and change to long pips later, would i still play the same action, or should i start with long pips, don;t know much about pips so i hope some one can help me, i have tried 388C, Dawie? and Neptune, long/p, and 729,755, which i liked the best, seems to have more control, or maybe i was just lucky, and the other thing is, i tried all those pips in a mater of 4 week, yes i know i am stuped, and i have not given any of them a chance, mind you i don;t even know how to use them, which does not help, i will be reading with interest but wont be able to answer your questions because my neck gets a bit sore when i am typing, due to an injury, but all your help will be very much appreciated, and as they say in Australia have a good day. Batman. P.S. have ordered Dr/N, Ferno, only because they where cheap, would they be better than the others?????
