Personally, my opinion of using the flow-thru sensors versus the small cap sensors mainly is the difference in the size and weight of the flow-thru with very little benefit. You have to unscrew a cap from either one to add or remove air so why not just unscrew the small cap sensor versus having all of that weight flying around on the outside of your valve stem. But everyone is entitled to their opinions.
The "T" is a good idea BUT it is just one more place for a possible leak to occur.
My sensors are always off the valve stems when not in use. That way they don't grow legs or use up the battery prematurely. I don't remove them until I am at a place that I plan to stay for awhile.
BTW, I did not choose either one of these TPMS systems. But if I had to choose between them I would have gotten the TST. They are one of the two BEST brands that are the in the TPMS business.
I chose the other brand.
