Suggestions for triple strike technique?

Hi all.
There is this one groove I like to play over a certain song. It goes like:
OtStOOoooOttStOS
RLRLRLRRRLRLRLRL
t=touch, O=open on conga, o= open on tumba
All strikes are played as straight sixteenth notes.
The point is the three opens in a row on the tumba.
The beginning and the end could variate but it only sounds right when the low notes are there.
The problem is when the tempo is high enough I start to lose accuracy on the three opens.
My question is what would be the most productive way to get better at it.
The options I have in my mind are:
1. Just keep on practicing the 3 single notes in a row.
2. Develop my double strike technique to take away some of the hand movement. I kind of know how do double strike but it's not nearly as clean and controlled as my single strikes.
3. Cross my left hand to the tumba to do RLR instead of RRR.
I don't consider third drum an option at this time because it would mean more to carry and practicing technique is fun anyway.
Any input is appreciated.
