What size should I...

[wilomn]

I meant better it be 15% than 10%. 30g should be just fine for a 200g snake.

Wee bit argumentative.

Actually not at all.

However, you seem to have a habit of writing one thing and meaning another OR, getting defensive when someone points out that you have, once again, written one thing and meant another.

It's YOUR responsibility to be correct in any advice you give, not the recievers to know that you have, once again, written one thing and meant another.

While mind reading is an option, I prefer not to use it in general. The stuff cluttering some peoples minds is just no fun at all.

I'm pretty sure you could do better if you wanted to. Maybe if you took two breaths between writing and hitting submit and used the time those breaths took to re-read what you have written to see just what someone else may think of it.
