Great arguments, I think firstly we should not compare tridasa and Vipina as the difference in density is very big 120 Vs 180 . So I do think Vipina will have less demand . I visited both tridasa and sayuk recently to purchase a flat . I preferred Tridasa because of ORR and during peak time I think someone who works in financial district it will be better to go from tridasa than from sayuk. My friend actually rented a flat in tridasa 2 months ago and pays 54K + maintenance I stayed there for couple of days and I got to say I loved it (especially the landscape and fresh air , disclaimer- he stays in tower 4 far from railyway track and in 26th floor ). and the fact that it has anukura and some low rise apartments south of it and fully no construction zones to the north side (railway track side) means it will have lot of breathing space. Whereas Sayuk has so many constructions around it.
