On standard coping i use 3/8" it's small yet wide enough to get a small joiner into amd possibly use a grout bag if needed. I wouldnt go smaller than 1/4" the tighter the joint the more perfect the cuts need to be. In MD you have freeze cycles so you shouldn't just butt them water will get in amd pop them down the road. Don't forget to caulk under the front and I always seal the coping before I mud them
