Sonic Homing Attack is really bad. I has start up that you can react to and negative priority meaning that unless you aren't fast enough to get your attack out there, at best homing attack never win, and at worst it will trade. It's really not that good. Blast attack on the other hand...
Fthrow is okay. Positional stuff. Put them off stage. Same with Bthrow. Uthrow/Dthrow are infinitely better. Dthrow for tech chases and uthrow for juggles. Bad DI on fthrow does give you a great positioning.
Speakin' of scrubby tactics, you ever find a use for RARing with Sonic's B-air? Since N-air ain't shit like it is in vBrawl, I've never felt like I need to RAR.
Hey, MR's Marth was able to Counter my Aether three times in a row. That shows that I'm still a scrub even if I don't intentionally spam it. -_-
Unless you're using Blast attack for Hardreads, using nB at all for reads is not a good idea. Tech chase grabs all day! Or if possible, dash cancel dtilt/dsmash.
Off stage is okay. It has it's moments where it's a good idea, but usually it's better to use an aerial or spring.
RARing is something that I don't do too often outside of WDs. It's a style issue, because I prefer doing moonwalk bairs instead of RAR bairs haha. RAR Bair is a good thing to do when spaced since it can be hard to punish, unlike nair which is babies to punish.
