Help Pruning

Hello friends.
I have a Charles grimaldi on my deck in a huge pot. It was growing just like I wanted, 1 main stalk w/ 1 "Y" then another "Y" shows up. I'm trying to get this guy to stretch out taller. Do I want to let the plant Y off as it likes? It's a 2ft tall brug and has plenty of buds below. Should I leave the Y if I'm going for a taller brug? Also, would I be promoting another Y via pruning off this 1 like in many other plants? I'm posting a couple pictures so you can see what I mean. The 1st is a top view of the main Y and how 1 side is trying to Y off again

Here is a side view

I hope you can invision what I'm wanting to do with this guy. Since its a deck plant, I don't want it growing much wider I don't think. Should it stay or should it go and why?
I wonder why 1 branch Y'd and the other is justy shooting up? I just can't decide which will look the best and which is best for the plant. I'm in a very indecisive place today so will you guys decide for me? LOL
Thanks, Jeff

For this season I would leave it alone. If it gets a basal shoot, let it grow a foot or two and then root it. The basal will make a tall tree for next year. I'm afraid if you start cutting off the Y's you won't get bloom and probably no more height anyway because the plant has already made that all important first Y and everything above it will be considered flowering region.

AHHH I see. That makes sense. I have a couple basal's on my Frosty pink that I'm letting grow out. I pruned off several smaller sprouts from the main 2 branches and am rooting them.
I'm so excited, I found the fastest way for me to root brugs.
I just stick the end that I want roots on in my aquarium and cover that root area from light. I have 4 TINY cuts in there maybe 2-3 inches long and they rooted in 4 days! Just baby roots mind you, not enough to where I'm ready to pot it though. I knew they were easy to clone but WOW, this is beyond easy. These root faster than my philodendrons I keep sticking in there and I didn't think anything could root faster than my phil's.
Please keep this great info coming, you all are teaching me so much!
