Again, more "biology" and physiology jabber woke. I can show you a number of trees that bloom profusely year after year but set little to no fruit set.
Bullie without taking growth habbits, production issues, health into consideration... How to rank the Pina Colada in terms of flavor??...screw the small mango and big seed factored into there.
It can be very good if left to ripen to the proper stage prior to harvest. Would I rank it in the tops, don't think so. Texture is very soft. Picked to early, it is very chalky and will not have the proper flavor profile it should have. If space is limited and a factor, I would think hard about planting one. If space is more on the unlimited side, then stick one in the ground.
As for small mango and big seed, I am also not in the boat. Its all about the quality first. Sweet Tart is smaller in size with an obnoxious seed but I will highly recommend it because of its flavor. I would rather eat two amazing mangoes than one average mango just based on flesh to seed ratio.
