im set on getting new pedals, cages and straps as one of the first mods to my FG (function over fashion), but i have a few questions, statements and concerns i would like to address.

doublestraps:
first of all, there is no ****ing way im going to spend 100 on double straps. no offense, im sure theyre worth it, but i just dont have the money. i found a few less expensive options online, i am wondering if anyone knows anything about these dimension doublestraps, as there are no product reviews on the site. i know there are white synthetic leather at ben's and black (might be synthetic, doesnt say) ones i saw on another site which were "laminated" which im guessing helps them hold up over time? not stretch etc?

cages:
from what i can tell just about everyone rocks some sort of metal cages. can anyone tell me the advantages over plastic? im sure metal doesnt need to be replaced often, but the plastic ones ive found (built for doublestraps) are stupid cheap, so replacement is whatever. the main reason i ask is because sometimes im doing (read: attempting to do) tricks and am a bit nervous about getting my feet out quick enough to catch myself from eating ****. so, im thinking i can ride on the non strap side of the pedal when i want to and not care if the plastic cages are scraping, or at least not as much as i would if they were metal....

pedals:
i have really wide feet, not like some sort of yeti (lolz), but as a point of reference, when i was younger i would have to wear the widest hockey skates they made, and even those were cramping. my feet are wayyy to wide for the pedals i got with the bike. they hang over the edge like crazy. i have seen the MKS whatevers, theres lots of em, but they all have these crazy teeth that are going to destroy my sneakers. so any rec's on a wide pedal without the teeth?

i realize this post was of biblical proportions, but i would really hate to waste money on bad parts. please help.
