I think the answer is yes with a but. They both will grow rapidly in the first year, and pbass will slow down after 12". The TSN will still growing fast until up to 24", then it will slow down. It's the time between year 2 and 4 that's most critical, that during this period the TSN is not more than twice as long as the pbass. But eventually when the pbass reaches to 18"-24", TSN will most likely max out at 36", then they both can be together for life.
