Interestingly though the Su-35S has demonstrated the capability to carry R-77-1s on the outermost underwing pylon on more than a few occasions, I wonder if this incurs any significant weight penalties just to carry 2 more R-77-1sIMO highly unlikely and given what BS is currently being spread by some I won't give much on this claim! The PL-15 is IMO clearly too heavy for the wing-tip pylons and as Blitzo explains, the J-15 already has more than enough other options to carry more than enough PL-15.
