I buy different styles of plastics in the same color in my favorite go to colors. Price may influence a little bit on what I buy but I am usually more concerned on if they have the type or style I am looking for. As far as tubes go I don't think the brand makes a lot of difference. I will tell you that I buy ones that have heavy salt on them. They will out perform the plain ones anytime in my opinion.
I try different types & colors till I find something that works. Oh and some people on here swear by Bang spray scent.
I will recommend black/chartruse; Purple/chartru;Blue/white;chartruse w/pepper.
Oh I almost forgot you better have some electric chicken on hand in case you meet up with Ole Silver Sides.
