What are the best skateboard pads?

Whenever I buy skateboard pads they are too small too big I need ones that fit my leg and elbow shape and it won't slip and slide. Right know I'm using the strap triple 8 pads and there not working out to well. This summer I'll be learning how to skate again at my skatepark I need the right skate pads. I'm a girl so my legs and arms r wider then guys and I have alot of baby fat still. :( I was looking at smith scabs which I like but to expeincive. I don't want anything that's alot of $. I need a pair of pads that will stay in place and be the right size for me not to big nor small. I'm also trying to find those pro skater pads that X Games skaters wear and Tony Hawk. They r strap ones with the white cap but I don't know if they r good or not. I don't fit in junior sizes that well I'm better with adults. If u can give me a website that would be great. I also like these called 187 pro pads they keep on ur knee and they slide good if u fall on a ramp but there $70 for knee pads not both knee and elbow. Please help?
