Ive been shooting with Canon for about ten years now, started on an old Rebel and eventually moved to the 70D which I used until the shutter literally gave up on me last month. I just picked up a 90D and the image quality is amazing but I am honestly struggling with the ergonomics and the data speeds. The body feels a bit small in my hands compared to what Im used to and my pinky finger just hangs off the bottom which makes long shoots pretty uncomfortable.

I am looking into getting a battery grip but Im torn. The official Canon BG-E14 is like 170 dollars most places and Im wondering if anyone has had good luck with the third party ones like Neewer or Vello? I used a cheap one on my 70D and it used to lose connection mid-shoot which was a nightmare, so Im a bit nervous about going cheap again but I also have a wedding coming up in three weeks in Seattle and Ive already spent a ton on the new body and a couple of lenses.

Regarding memory cards, the 90D supports UHS-II but I keep seeing conflicting reports online about whether it actually makes a difference in the real world. When Im shooting bursts at 10fps, my current SanDisk Extreme Pro (UHS-I) seems to choke after about 20-30 shots and then the camera just sits there blinking while it writes to the card. Its driving me crazy.

My main requirements are:

• A grip that wont disconnect or feel creaky when Im using a heavy lens like the 70-200mm
• Memory cards that can actually handle the 4k video without overheating or stopping
• Total budget for both is around 250 bucks if I can swing it

Do I really need to shell out for the V90 cards or is V60 enough for this sensor? And is the Canon grip actually worth the 3x price jump over the Vello version? I really dont want to have equipment failure during the ceremony...
