For the price you could probs just buy both, i take both on the field with me and if i break a ball and have time i use the pull threw i do, then fluffy the barrell, as said before though this is time consuming and while playing air you will probs not have time.
The straight shot is a good idea but as said before they are quite awkward to run about the field with, sticking it down the pod pack is probs the best way to carry it.
Them squeegies are good value as you just rince them off and will last a hell of a long time, you can pick them up for like 3 quid so its always worth having 1 handy even if its just used when your setting your marker up etc.
Hope this helps
