Can't charge and take along energy attacks when going through rifts

Switching the direction of his Rifting, he miscalculated his timing, holding a ball of ki in his hand and failing to release it as he entered the next Rift. 'Damnit, clumsy oaf!' he roared at himself, coming back through, his hand empty, though still poised to cradle the ki ball. Growling in minor frustration, he reset his pace, continuing to simultaneously speed through Rifts and defend.

'Huh?' Goku thought. 'He was using his own ki to deflect my attacks, but then, when he should've fired one, it looked like he lost it.' Seeing the older Saiyan exit the rift empty handed, when he knew he'd had a blast going in, was something of a relief. After all, Vegeta made mistakes just like any other fighter.

'Wait a minute...that's it!' he thought triumphantly, having deciphered one of the Rifting technique's limitations. 'He can't charge attacks and take them through like I can. Score one for Instant Transmission!'
