sorry if this is something that's been posted before... i'm new to these forums so i don't know much of the technical terms to what i'm about to describe but i am completely committed to learning so i hope my questions don't get too annoying! 
anyhow, my main character from Melee was Sheik and my bread and butter strategy was to run up and sprint attack my opponent(s) and start off a combo of smash hits, and similarly with fox/pikachu. But in brawl i've been having a tough time transitioning and i've observed that almost every time i use the same method, whatever fighting is going on will always override the sprint attack so i just end up getting caught up in someone else's attack, and it also seems like the sprints aren't as fast so people just know it's coming and can react. So this kind of playstyle for me seems to be getting killed especially by the mid-range big hitters and i was wondering if anyone can give any feedback or advice with the transitioning from melee playstyle to brawl.
also, i've been browsing around some of the character forums and so far the mains i'd like to learn to use are Toon Link and Lucario (and sheik if it turns out she wasn't as nerfed as i thought based on my first impressions) but again, i'm farily new to the terminology so i don't know half the stuff that's being talked about, so if anyone can give me some general playing tips for these two characters i'd appreciate it, thanks!
