krabi krabong and escrima

Woof All,

concerning the similarities between escrima and krabi krabong in their concepts of weapons fighting, i would like to ask a few questions to those of you having enough insights in both of these arts to answer
-is it based on the same concepts, i mean one of the main combat concept in escrima is "to go with the flow", does one find such a concept of paramount importance in krabi krabong weapons fighting ?
-how does krabi krabong deal with both hands armed, i mean is there such drills as sinawali taught within the system? assuming yes, is the idea of sinawali(waving motion) and the fluidity it tries to emphasize seeked in those drills or just common ability to yield a weapon in both hand at a time?

thank you in advance,
Yoann
